SPECIFICATION T0 a/ZZ whom it may concern:

Beit known that we, MICHAEL G. ScHAUEn and ALDEN A. BARTLETT, of PipeStone, in the county of Pipe Stone and State of Minnesota, have inventeda new and useful Improvement in Band-Cutters and Feeders for Thrashers,of which the following is a full, clear, and exact description.

Our invention relates to an improvement in band cutters and feeders forthrashing machines, and the object of the invention is to improve uponthe construction of the band cutter and feeder for which Letters Patentwere granted' to W. G. Huntington, February 24, 1891, No. 446,973, andto this end, the invention consists in the novel construction andcombination of the several parts, as will be hereinafter fully set forthand pointed out in the claim. y

Reference is to be had to the accompanying drawings, forming va part ofthis specification, in which similar gures and letters of referenceindicate corresponding parts in all the views.

Figure l is a vertical longitudinal section through a portion of athrasher and the iinprovedband cutter and feeder applied to the machine,the section being taken onthe linev 1-1 of Fig. 3.l Fg.`2 is a sideelevation of the attachment. Fig. 3 is a partial plan view and partialhorizontal section of the attachment, the section bein gtaken on theline 3-3`ofFig. 1; and Fig. 4 is a detail perspective view of a portionof one of the feed arms and the sickle' knife attached to it.

The dust box A, is preferably made open at the bottom and -is closed atthe top by two covers 10 and 11, hinged in such manner that they may bereadily lifted to expose the interior of the dust box when desired, butwhen the covers are closed dust cannot pass out through the upper partof the box but is compelled to enter the thrasher and pass through orover the thrashing cylinder, thereby preventing the attendant located atthe feed opening of the dust box from becoming choked, or otherwisetroubled bythe dust. The box' at its top is preferably given a downwardinclination; that is, an inclination downward in direction of thethrasher, and the box and the thrasher may be connected in any suitableor approved manner. A feed opening is located in front forming. part orLetters Patent No. 528,396, dated october 30,1894. Apprenti@ nea nachz5, 189s. lsain Na; 467.619. (No moan.)

Aof the dust box and is designated as 12, and at leach side of thisopening beams B, are secured, the said beamsbeing preferably in twosections 13 and 14. These beams are adapted to form a` frame for acarrier O, which carrier is adapted to convey the material to bethrashed into the dust box to be operated upon bythe feed devices andknives. i The beams B of the carrier extend horizontally outward fromthe dust box, and the two sections are held end to end when the carrieris yin service by means of 1a hook or clampl, as shown in Fig. 3, or anequivalent device. A

Each beam B, is preferably provided with a sideor guard board 16, theboard being in .as many sections as there are sections of the beams. Thebeams are connected by means of a hinge 17, preferably a rule hinge, sothat when the two sections are in a horizontal position their opposingends will abut, as shown in both Figs. 1 and 3; but when the attachmentis not in operation and it is desired to remove the thrasher from oneplace to another, the outer section of the carrier may be droppeddownward and carried practically vbeneath the dust box and therefore outof the way, enabling the team to bev attached to the pole of thethrasher without inconvenience.

Between the beams B of the carrier O two drums 18 and 19, are placed,the drum 18 being at the inner end of the carrier and essentially withinthe feed opening of the dust box, while the drum 19, islocated at ornear the outer end of the carrier, and the two drums are adapted tocarry and support an endless belt or apron 20,'the Ysaid apron beingordinarily provided with a slatted outer face, and the upper stretch ofthe apron or belt is prevented from sagging downward by cross bars 21,engaging practically with the inner face ofthe belt or apron, as islikewise 'shown in Fig. l, the said cross bars connecting the side'beams of the carrier.

Within the dust box a slanting frame D, is located, the frame beingessentially at the central portion of the box; and the said frameusually comprises an upper and a lower transverse beam, designatedrespectively as 22 and 23,' and a longitudinal beam 24, which connectswith the end beams near the center of the latter, as is best shown inFig. 3. The center beam 24 of the frame has secured upon it at suitableintervals apart two journal boxes 25, and each of these boxes is adaptedto receive a crank shaft designated respectively 5 as 26l and 27, theouter ends of the crank shafts being journaled in boxes 28, located inthe side portions of the dust box. Each crank arm of each drive shaft ispivotally attached to a feed arm or bar 29, the arms or 1o bars beingarranged parallel to each other at suitable intervals apart andlongitudinally of the dust box; and the arms or bars are s located withrespect to the crank shafts that when one of them is in an upper orrearward I position another will be in a forward and ,lower position, orvice versa, and others will be in positions intermediate of the upperand lower and forward and rear ones, the arrange ment of the cranksbeing best shown in Figs. 2o 1 and 3.

The finger arms or bars 29, are provided upon opposite sides with bladesor knives 30, and these blades or knives are sickle-shaped, as shownbest in Fig. 1, and are arranged 25 in groups of two or more, andusually four groups are placed upon the feed bar, two near the front endand two near the center. The knives, as shown in Fig. 4, comprisevirtually plates a. of an angular character, a body bar a to which theknives are connected or integrally affixed, and straps a2, which emanatefrom the body bar and are adapted to be passed up the sides of the feedarms or bars and over the top thereof, both the body bar and strapsbeing secured to the arms. This construction of knives provides for theremoval of individual groups of blades for repair or replacement ofbroken sections or cutters.

Each feed arm 29, is provided at its rear end with a nger known as akicker, the fingers being adapted to assist the material that has beenacted upon in its passage to the thrashing drum E of the thrasher.

In connection with the upper feed devices 29 an auxiliary and lower feeddevice is used,

the latter being in theshape of a board 31, the board being locatedpreferably parallel with the frame D and the top of the box. Thus theboard is given a downward inclination from the receiving opening towardthe cylinder E of the thrasher, as shown in Fig. 1. The upper face ofthe board is corrugated or otherwise roughened, and the board is adaptedto have a longitudinally reciprocating movement, this movement beingimparted to it by a crank shaft 32, which is directly connected with theforward end of the feed board, as shown in Fig. 1, the said crank shaftbeing journaled in the forward portion of the dust box, while the inneror free end of the feed board is made to slide upon the extension 33from the sector 34 of the thrasher.

The driving of the various parts is aecomplished in the followingmanner: A band wheel 35, is secured upon the outer end of the thrashingcylinder shaft, andis connected by a belt 36 with a large band wheel 37,located preferably upon the forward upper crank shaft 26, as shown inFig. 2. This shaft is also provided with a small sprocket wheel 38, andthe said sprocket Wheel is connected by a chain belt 39, with a smallerwheel 40, located upon a shaft attached tothe outer face of the dustbox, which shaft has also loosely mounted upon it and connected with thesmall sprocket gear 40 a gear 41, and this Gear 4l, meshes with a likegear 42, fast upon one trunnion of the inner carrier drum 1S, and thesaid gear 40 likewise meshes with a gear 43 of like size secured uponthe crank shaft 32 carrying the feed board 31. Thus the various partsare compactly and simply geared together, and are operated in perfectunison.

The auxiliary or lower feed board 31, it will be observed, will force orcarry the chopped or divided material to the thrasher cylinder evenshould the upper set of feed devices fail to act, but when the two feeddevices act together a perfect and regular feed is secured although theknives are carried only by the upper feed devices.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent- In a band cutter and feeder the combinationwith a feed bar and its two crank shafts, of two pairs of cuttersmounted thereon each cutter comprising the plates a, body bar a', theknives 30 on the' bar a and the angle straps a2 projecting from the bodybar and extending upwardly along the sides of the feed bar and over itsupper face, substantially as set forth.
